That’s a Bingo!

Monkey Island!

Green bunny with a gun.

I’m torn on the whole no downvote button thing (I missed that when I signed up), but you can be still nice while having a discussion and disagreeing with people.

I would argue that the downvote button can lead to exactly what you are describing though, no disagreement or conflict.
Someone posts a unpopular opinion, a bunch of users downvote it to hell and poof!, no discussion or exchange of ideas. Just out of mind, out of sight.
